The DEFAPPL option on the LUMAP statement allows a host VTAM® application to be mapped with an LU name or LUGROUP name instead of using DEFAULTAPPL. The LUMAP-DEFAPPL combination is treated just like DEFAULTAPPL when a Client Identifier matches the LUMAP statement. The LUMAP-DEFAPPL combination also supports the LOGAPPL, FIRSTONLY, and DEFONLY parameters that are used by DEFAULTAPPL, PRTDEFAULTAPPL, and LINEMODEAPPL. The LUMAP-DEFAPPL combination is a powerful statement when used with multiple LUMAP statements for the same Client Identifier. If the LUMAP-DEFAPPL or PRTMAP-DEFAPPL statement is coded and the default application is not available, an error screen will be sent to the client whether or not MSG07 is coded.
The PMAP option on the LUMAP statement allows assignment of connection parameters based on LU or LU group name. When the LU is assigned, the parameter values specified in the PMAP PARMSGROUP will override the parameter value specified in TELNETGLOBALS, TELNETPARMS, or PARMSGROUP mapped to this connection's Client Identifier. For example, any client in subnet 9.0.0.0 that specifies the LU group LUGTSO will immediately have a session initiated to TSO with the LOGAPPL function, and the TIMEMARK time will be set for two hours instead of the default three hours.

LUMAP LUGTSO IPGRP9 DEFAPPL TSO LOGAPPL PMAP PGRPT2 An LUMAP-DEFAPPL defined default application name is always used if specified, regardless of USSTCP mappings. LUMAP-DEFAPPL has a higher priority than any DEFAULTAPPL or USSTCP. The connection parameters assigned using LUMAP-PMAP will override any other setting of the parameters. However, not all parameters have a meaningful use by the time the LU is assigned. For example, NOTN3270E controls whether or not Telnet should negotiate for TN3270E. That negotiation is done before LU assignments. For information on which parameters can be properly applied with LUMAP-PMAP, see the parameter table in z/OS Communications Server: IP Configuration Reference.
The PRTMAP statement supports PRTMAP-DEFAPPL and PRTMAP-PMAP in the same manner as LUMAP-DEFAPPL and LUMAP-PMAP.
